Communication
This section contains all the settings relating to the connection of
KAPTOR
MINI
to the
Internet and the data transmission.
The instrument, through the integrated modem, has the possibility of:
✓
Send historical data stored to the server via GPRS
✓
Send alarm events to the server via GPRS
✓
Send alarm events via SMS to multiple users
✓
Synchronize the time with the server via GPRS (via HTTP or NTP server)
✓
Send your configuration to the server via GPRS
It is possible to combine the activation of each single function to make the instrument perform what you
need.
The modem supports two different ways of sending data:
1.
Through HTTP requests with GET method, according to a proprietary protocol
2.
By CSV file transfer using FTP protocol
The sending protocol over HTTP, involves sending strings similar to the following:
GET/savedata.php?id=100&ts=201806301550&Q=125.6&AN1=1.2
This transmission means the system with ID (system identification number) 100 at 15:50 on 30/06/2018
recorded a flow rate (Q) of 125.6 and an analogue input 1 (AN1) of 1.2 in reference to the measuring units
set in the instrument.
The script that can be reached on the server page must therefore extrapolate and process the desired
information from the received string.
Transferring files via FTP, on the other hand, involves sending separate files containing all the information
stored by the instrument, i.e. logs, events and instrument configuration.
